We're still waiting on a release date for the Ant-Man movie as well. As the Ant-Man logo and test footage were revealed at the SDCC, maybe it could be a part of Marvel Studios' Phase 2 plans. More than likely Phase 3, I would imagine.

The Avengers 2 assembles May 1, 2015 with Iron Man 3 on May 3, 2013, Thor: The Dark World on November 8, 2013, Captain America: Winter Soldier on April 4, 2014, and the Guardians of the Galaxy movie on August 1, 2014.
